-/* Okay, this is some magic that I worked out and the reasoning behind it...
-
- The biggest problem with any USB device is of course: "what to do
- when the user unplugs the device while it is in use by an application?"
- We have several options:
- 1) Curse them with the 7 plagues when they do (requires divine intervention)
- 2) Tell them not to (won't work: they'll do it anyway)
- 3) Oops the kernel (this will have a negative effect on a user's uptime)
- 4) Do something sensible.
-
- Of course, we go for option 4.
-
- It happens that this device will be linked to two times, once from
- usb_device and once from the video_device in their respective 'private'
- pointers. This is done when the device is probed() and all initialization
- succeeded. The pwc_device struct links back to both structures.
-
- When a device is unplugged while in use it will be removed from the
- list of known USB devices; I also de-register it as a V4L device, but
- unfortunately I can't free the memory since the struct is still in use
- by the file descriptor. This free-ing is then deferend until the first
- opportunity. Crude, but it works.
-
- A small 'advantage' is that if a user unplugs the cam and plugs it back
- in, it should get assigned the same video device minor, but unfortunately
- it's non-trivial to re-link the cam back to the video device... (that
- would surely be magic! :))
